Sažetak
Forest management implies activities that affect spatial structure and distribution of trees as well as the diversity of forest tree species within the stand. Biodiversity and spatial structure are commonly described with qualitative descriptions or quantitatively indexes (estimators) of biodiversity or spatial structure developed for this purpose. Aim of this work is to quantitatively analyse species and spatial structures on plots in mixed stands of Common oak and Hornbeam using BWINPro program for analysis and prognosis of forest stands. Elements of structure were quantified with indexes of species composition (species diversity, Shannon index, Evenness) and of spatial distributions (Clark & Evans index of aggregation, Pielou index of segregation).
